update on 6V-4.5AH SLA rejuvenation

Hi folks, the results are getting better and better. After the second conditioning cycle so far, I am now able to run the same bulb load as before but this time the battery powered the load for 3 hours where as the after the first cycle it only powered it for 1 hour, 10 minutes. Though with the almost 2 watt load of the small bulb the battery should last about 15 hours, so it's coming along.

Hi folks, Hi blackchisel, thanks for info. yes the normal charger isn't charging the battery much anyway, its peaking after only 5 or 10 minutes so yes more conditioning needed. I wasn't timing the charge time with using the pulser, I was only timing the discharge, so I will take note of the charge time also now. Thanks.

Hi SkyWatcher Don't rush with conventional charger. Try to format (condition) battry with radiant some more. See if charging time is decreasing each time and resting V, without load. You may have interesting observations.

It is a small 600 VA ups. Output 220V @2.6 A =572W.
It only takes a 7Ah battery and is probably only to protect your pc against power dips or give it time to automatic shut down.
Unfortunately to supply 572W on the output it has to draw a lot of current from the battery. - yes, that's exactly this poor battery role and slow death - her destination.
Another thing I saw was in the Hector Perez rotoverter teachings where they said that a lead acid battery should not be charged more than 12.7 V.

IMO, lead acid battery should be charged to 2.40V per cell which will result in 2.25V resting and should never be discharged below 2.09V per cell. This is based on 6 cell battery. Battery manufacturers should supply data charts with recommended charging/discharging details. During charge and discharge process battery should remain cool (ambient).

Hi folks, sounds like your results so far are similar to mine, nvisser. Ok, the battery has desulphated enough and its impedance low enough now to put on a normal charger, i did this and it is not taking a full charge yet, so it will need more condition cycling. Though so far I am able to run a small light bulb load for just over an hour drawing 280 milliamps starting at 6.1V and slowly dropping for 1 hour and 10 min. then dropping fast, so it is looking good so far.

5 A discharging for 7Ah battery is way too much. V-tech

update on 6V-4.5AH SLA revival

Hi folks, the rejuvenation is going well, it now holds the particular bulb load I've been using at 5.84V steady and with no load is sitting at 6.25V though would probably drop some when settled. Loos like I will soon be able to put this on a normal charger, the question is why should I since it will just sulphate up again down the road. Anyway, results are looking very good so far.

@SkyWatcher

"all this batt. needed was extra blasting power to start to loosen or transform the corrosion inside" Conventional chargers are pushing current into the battery often causing excessive gassing and heating. Unless circuit is meant to transform other form of energy into heat, any heat "produced" during transformation can be seen as waste of energy. In case of battery it's harmful and should be avoided. Charging with pulses and relatively small current allows the HV puls to penetrate non conductive sulfuric "coating". This coating cannot be "shaken off" or penetrated by conventional charger.

Hi folks, thanks for the information. I'm blasting the battery again today and it's definitely desulphating this battery today when checking resting voltage it is now at 4.6V from 1.6V, but yes probably not all dead leads can be brought back to life. It is interesting to note though that all this batt. needed was extra blasting power to start to loosen or transform the corrosion inside. Will let you all know how the revival goes.

Hi, I got about 15 sealed lead acid from local health care unit. They have to replace them every 2 years, regardless of condition. I found one dead and there is absolutely nothing in my powers to get her going. She was sitting on 4.8V. All others worked fine despite their resting V on the beginning was way too low to be healthy 10.5V - 11.7V. They don't cooperate quite as good as deep charge lead acid, at least for me.

Gel ( sealed lead acid) batteries

I forgot to mention; gel batteries may dry with time or because the way they were treated (pushing too much current or discharging above their rate). There is no (known to me and practical) way to revive them.

@nvisser

5 A discharging for 7Ah battery is way too much. Try to keep discharging ratio at or below C20, which in this case will be 0.35A. Some batteries are dead, I mean dead, dead and there is nothing you can do about. About 70 -80% average can be rejuvenated. Lead acid need electrolyte to be on marked level. Electrolyte doesn't dry, only water. acid will remain embedded in plates and only distilled water should be added. Batteries with visible swelling or cracks are waste of time. There maybe also one shorted cell which will prevent from reaching nominal V. There maybe build up of fallen pieces on the bottom, shortening cell or cell plates plastered together. SSG is charging with negative pulses and batteries not suppose to be switched. If you use a converter - capacitor, than you can swap primary with charging. I'll still allow at least an hour between end of cycle and connecting back to the circuit. There is still some charging present after disconnecting. Ions are heavy and need time to slow down. Otherwise it would be like shifting from reverse to drive without making complete stop. I'm still experimenting with my Solid State, waiting for deep cycle solar batteries. Other good ones are golf cart (6V). Both are truly deep charge. One more thing; automotive batt. labels are misleading; 100Ah batt. may have 80 at most so you have to calculate C20 on real value. Some old batteries may seat on low V for couple of weeks before starting to climb. They may need several - 10 -30 charge/ discharge cycles.

I am currently trying to rejuvenate a 12v 7ah battery that came out of my ups. It was sitting there for 3 years with a constant electron charge of 13.8v and just died. With a sudden power dip it could not even keep the power to my pc for 1 sec.
When I took it out and shorted the terminals nothing happened. No current flow.
I connected it to a small ssg with the one diode , no caps or pulsing, spikes straight to the battery, over a weekend.
It came back to life but it did not keep the charge for long After I charged and discharged it the current way in the ups a few times It could supply a current of 5 amps for 2 minutes with a 60w 220v bulb on the ups output.
It is now back on the ssg supplied by a pc power supply with 24v (between 12v and -12v) I will report in a few days time what the results are
I know there are a lot of senior guys on this forum that has done this before and will be able to answer some questions
Some say that supplying a battery with the radiant pulses destroys it
Some say that charging the same battery the Cole way by switching destroys it
Some say with the cap pulsing method you should not exceed 23v for a 12v battery while it looks like John Bedini did it with high voltages on the Bedini/Watson generator
Which make me wonder sometimes why I still try to get that machine going?

Hi Tyson,

On really high Z gel cells I've had success by putting a high voltage cap in parallel with the charge battery until it starts to take a charge without it (talking about a standard SSG here). Sometimes a gel cell needs water to take a charge but I don't know the specifics of adding water to a sealed gel cell.

Hi again folks, quick update based on my last post. I am now seeing results rejuvenating my 6V-4.5AH sealed lead acid battery. I was using too low of an input too see any results, I was initially using 100 millamps at 12V for the joule thief charger and I've now increased the input to 750 milliamps and am able to hold a load at 3.5V and it is steadily increasing, whereas at the 100milliamp input i saw no load handling ability, it would just drop straight to 0 volts. So this is very encouraging and I do believe this battery can be fully recovered. By the way the joule thief is using 18 gauge wire on a laminated choke type core. let me know what ya think.
